Answer:
- gas
- liquid
Explanation:
Part of the definition of gases and liquids is the ability to flow, so this answers your question.
Why does this not apply to solids? The cells in a solid are closer together with less room for movement, so they do not "flow" like gasses or liquids. You can think of the device you are asking this question on versus the water in the ocean.
<u>Note</u>: Gas can still flow, but it does not flow the same as water. It depends on what you are being taught for if gas flows or not.
-> Liquid flows from high to low only, while gas can flow in all directions
Have a nice day!

Answer:
Protist
Explanation:
Protist are prokaryotic organisms
Answer:
In humans, genetic variations are caused because humans reproduce by a sexual life cycle which is termed as meiosis. In such a life cycle, the offspring receives half the chromosomes from the mother and half from the father. Crossing over and random assortment of chromosomes are two phenomenons which occur during meiosis. Due to these two phenomenons, genetic variations are caused.
During crossing over, the exchange of DNA segments between the homologous chromosomes takes place which brings about the genetic variations.
They attach to the chromosomes, line them up during metaphase, and pull them apart during anaphase
